I was conducting a multicollinearity diagnostic analysis for a logistic regression using spearman correlation and VIF. Important detail:All the covariates are binary variables.Considering that when both(2) variables are dichotomous, a Pearson correlation coefficient is equivalent to the phi coefficient and to Spearman coefficient,would not be wrong write in the statistical analysis text(topic) that multicollinearity was conducted using spearman correlation or I have to change the words “spearman correlation” to “Phi coefficient”(in the text) to be 100% correct in terms of methodology description.? > REgards, > Marcos. > >> -----Original Message----- >> From: stoll@rice.edu >> Sent: Sun, 20 May 2012 16:24:41 -0500 >> To: statalist@hsphsun2.harvard.edu >> Subject: Re: st: Can Spearman's rho be used to measure of the degree of >> association between two binary variables ? >> >> A classic article in political science that compares a wide variety of >> measures for 2 by 2 tables is: >> >> Weisberg, Herbert F. 1974. “Models of Statistical Relationship.” The >> American Political Science Review 68(4): 1638–1655. >> >> -- >> ----------------------------------------------------------------- >> Richard J.
